PRODUCT DATA
OSCxx-UOW
Ultrasonic Ceiling Occupancy Sensor
BASIC OPERATION
The OSCxx-U is a low voltage occupancy sensor
that controls indoor lighting. The sensor fills the
room with continuous reflective high frequency
(ultrasonic) sound waves. Any movement within the
sensor’s range causes a shift in the original emitted
frequency. T
he sensor’s receiver identifies any change
in frequency
as motion and either turns the lights on
or maintains lights on.
APPLICATIONS
• Cafeterias • Classrooms • Hallways
• Filing rooms • Open areas • Restrooms
• Storage rooms • Open warehouses
• Workspaces • Executive offices
• Offices with cubicles
FEATURES
• Self Adjusting: An internal microprocessor
automatically analyzes, evaluates and adjusts
time delay and U/S settings for maximum energy
savings
• Custom off-white color matched for shaded ceilings
• Fast, simple in stal la tion: easy ceiling mount, three
wire con nec tion (low voltage) and twist-lock sensor
attachment for 360° rotation and flexibility
• Maximum reliability, low cost: digital circuitry uses a
minimum of components
• Small motion sensitivity: the ultrasonic tech nol o gy
provides excellent small motion sensitivity
• Non-volatile memory: learned and adjusted settings
saved in protected memory are not lost during
power outages
•
Timer Setting Feature: Automatic—30sec – 30min.
Test mode—6sec with auto exit programming.
• Walk-through: provides increased energy savings by
decreasing the time delay to 2.5min when someone
momentarily walks through the monitored space
• Wide coverage: units from 500 to 2000 sq. ft.
available
• Ambient light recognition: a light sensor prevents
lights from turning on when the room is adequately
lit by natural light
• Power base (OPB 15) available for line voltage
applications
• Ultrasonic (U/S) components: one or two U/S
transducers and one or two narrow bandwidth
receivers each 16mm in diameter. Frequency—
Crystal controlled to ±.005%.
• Device: rug ged, high-im pact, in jec tion molded
plas tic, off -white. Col or coded leads 6” (16.24 cm).
Timer Left In Test Mode - The
sensor remains in an 6 sec.
test mode.
False-On - The sensor
incorrectly turns the lights on.
False-O - The sensor
incorrectly turns the lights o.
An installer accidentally leaves
the sensor in the 6 sec. timer
test mode and the lights may go
o or on every 6 sec.
The sensor detects movement
in the corridor or hall way and
the room lights turn on.
The sensor does not detect
movement because an
occupant sits virtually
motionless at a desk and the
lights turn o.
The sensor automatically resets the timer
to 10 min . after 15 min of test mode..
After an initial movement is sensed,
if another mov ement is not sensed within
the timer setting then the delayed o time
setting is automatically reduced.
Condition Example Adaptive Reaction
If motion is sensed within a short period after
the lights go o, then the current delayed
o-time setting is increased.
